These pens, pencils and highlighters are always in my pencil case. I highly recommend them all. I'm based in Japan so I've tried to find the same ones I buy in Japan that are available in the US!
Best mechanical pencil. Quick tip - B lead is what I recommend for sketching. Surprisingly this is actually lower/midrange in terms of mechanical pencils on the market. It's a steal for how functional it is.

My favorite black pen. I prefer the 0.5 point but 0.7 is also available.

Second best black ink pen! I love these for the way they look!
